When I select a group of files as wanted, Headphones starts a search in the providers, stop when find the first file and pops a red message in the browser saying I didn't add anything.
Hmm... is this still a problem? You're selecting the albums on the artist page? And you have the downloaders set up, etc? Do you mind just trying in the latest version (if you're still using headphones)?
